This invention relates to certain newxand useful improvements. in}expansible link braceletsandthe pri1naryj, object thereof is to provideimproved meansjfor efi'ecti'n variation in the.lengthofithe same.

V A further object of the invention is to provide a device of thischaracterwhich can be applied to eitherthe central portion of thebracelet-or toone of the end links thereof.

The invention still further aims toprovide a device of this characterwhich can be easily and quickly operated to eflect length variation ofthe bracelet and which is positive andcertain'in its holding action.

In the drawings Figure 1 is a bottom plan view of the invention appliedto the central portion of a bracelet. e

Figure 2 is a like view showing theparts separated.

Figure 8 is a section on line 3-3 of Fig. 1'. r Figure 4: is a top planview of one end of a bracelet with the invention applied thereto.

Figure 5 is an end view of the'connecting member.

In proceeding in accordance with the present invention, a connectingmember is employed, composed of a casing or face plate 1, having sideflanges 2, the central parts of which are provided withintegral fingers3, the structure being preferably made of a single blank which is shapedinto the form disclosed. A plate 4 is formed with a pair of spacedhollow ribs 5 on each side thereof by bending or curling the side edgesof the plate inwardly. The plate 4 is spaced from the face plate 1 andthe fingers 3 are bent or curled inwardly to occupythe spaces betweenthe ribs as shown more clearly in Fig. 2 of the drawings. In this waythe plate 4 is secured'to the face plate 1. The ribs a are formed 'withspaced notches 6 on their outer sides forengagement with lips 7 thatextend inwardly from the sides of U-shaped latches 8, the latter beingpivoted at 9 to the inner bracelet, the lips being spaced rearwardly ofthe pivotal points of the latches.

The bracelet shown has its ends indicated at B is of the type formed ofplates 14 the sides of which arerolled to form double-ribs 10 althoughthe invention can be adapted to other types as is evident, andaccordingly 1926. Serial na ioaavog I i the ribs ai'e "telescopically,received the ribslO andthe lates 14 are received in-tlie' spaces betweent ie; face platell andthe Plate- 4. It will 'thus'be seen that theribs5scrve to guidegand hold the'ribs 10.against. lateral in'ov'ement,while the lips of theflatch es can beg-engaged in selected ones of thenotches 6 to thus impart the desired length to the bracelet. g g

In F i ure 4 amodified form of the invention is epicted and wherein theconnecting member l -is afiixeddirectlyto an outer end ofthe bracelet,or as shown to the usual hook I that engagesthe bail or loop (not.shown)"of the wrist watch: In this form of the invention, oneof'thelatches is of course dispensed" with and likewise the ribs of theconnecting member'can be shortened as de- Having thus described myinvent-ion what I claim vas new and desire to secure by Letters Patentis r i v 1. In combination with a bracelet ofthe double rib type havingends, a substantially U-shaped latch pivoted to'each of said ends, aninwardly extending lip on each arm of each latch, a connecting memberhaving side flanges and central fingers on the side flanges, and a platehaving a pair of spacedv hollow ribs on each side thereof disposedbetween the flanges of the connectingmemberv and receiving the ribs ofthe bracelet ends thereover, the fingers of the connecting member beingbent to lie in said spaces between the hollow ribs, to secure the plateto the connecting member said hollow ribs-having a series of notches ontheir outer sides to selectively receive the lips of thelatches. I

2. In combination with a-brace'let of the double rib type having ends, asubstantially U-shaped latch pivoted to each of said ends, lips on thearms of the latches, a connecting member, a plate having notched ribsthat are telescopicallyengaged with the ribs of the bracelet ends, andmeans to secure the plate to the connecting member, the lips of thelatch arms being received in selected necting member to telescopicallyengage each of. the bracelet ends, and means carried by the braceletends tolatch the latter to said first named means, said first namedmeans having a series of spaced keepers to engage said latching means.

4. In combination with a bracelet having attaching means on its ends, aconnecting member, means on the connecting member for engaging andholding said attaching means against lateral movement, one of said meansbeing hollow to telescopically receive the other, means carried byone ofsaid means to adjustably latch same to the "other, and means carried-bythe saidother means to engage the latching, means.

5. In combination with a bracelet end, a member having a pair of meansto engage saidend, each of the means having aseries of notches, and aU-shaped latch pivoted to the bracelet end having lips on each of itsarms to engage in selected ones of the notches, the lips being spacedrearwardly of the pivotal point of the latch. i

6. In combination with a bracelet having ends provided with hollowportions, a con necting member, means on the connecting member to engagewithin the hollow portions of the bracelet ends to hold the latteragainst lateral movement, securing means on the bracelet ends toadjustably secure the latter to the first named means, and means on thefirst named means to engage the securing means.

7. In combination with. a bracelet end, a member havingmeans to engagesaid end, said means having a series of notches on each side thereof,and a latch pivoted on the bracelet endhaving lips disposed rearwardlyof the pivotal point of the latch and formed to engage in selectednotches on each side of the first named means.

8. In combination with a bracelet and, a member havinglneans to engagesaid end, said means having a series of notches on each sidethereof, anda U-shaped latch pivoted at its free ends to the sides of the brace letend and having a pair of inwardly extending lips, formed to engage, inselected notches on each side of the first named means.

Intestimony whereof I have signed my name to this specification.
